Paper Abstract

Flame tomography of chemiluminescence is a necessary combustion diagnostic technique that provides instantaneous 3D information on flame structure and excited species concentrations. However, in most research, the simplification of calculation model of weight coefficient based on lens imaging theory always causes information missing, which influences the result of further reconstructions. In this work, an improved calculation model is presented to determine the weight coefficient by the intersection areas of the blurry circle with the square pixels, which is more appropriate to the practical imaging process. The numerical simulation quantitatively evaluates the performance of the improved calculation method. Furthermore, a flame chemiluminescence tomography system consisting of 12 cameras was established to reconstruct 3D structure of instantaneous non-axisymmetric propane flame. Both numerical simulating estimations and experiments illustrate the feasibility of the improved calculation model in combustion diagnostic.
